BYD Showcases DM-i Electric-First Hybrid Technology In India

BYD DM-i

BYD India, a subsidiary of the world’s largest New Energy Vehicle (NEV) manufacturer, has showcased its DM-i (Dual Mode Intelligent) plug-in hybrid technology in India. Positioned as a transitional bridge between internal combustion engines and pure battery electric vehicles (BEVs), the incoming powertrain technology targets long-haul efficiency with a combined cruising range exceeding 1,200 km.

With a global plug-in hybrid history starting with the F3DM in 2008, BYD has amassed over 8 million cumulative PHEV sales, capturing a 35 percent global market share in the segment. The technology's introduction in India is intended to expand BYD's domestic portfolio beyond its current pure-EV lineup, which serves a growing base of 14,000 customers via 48 showrooms across 40 cities.

Unlike conventional hybrids that rely on a petrol engine as the primary mover with electric motors acting as secondary support, BYD's DM-i architecture reverses this layout to operate as an Electric-First system.

The vehicle relies primarily on battery power across everyday urban commutes. The petrol engine operates secondary to propulsion, working as a silent generator to maintain battery state-of-charge or engaging directly only during high-load, high-speed scenarios.

The system manages energy distribution via three intelligent operating modes:

  • EV Mode: The vehicle relies entirely on the electric motor and battery pack, mimicking a standard BEV for zero-emission city driving.
  • HEV ‘Series’ Mode: For mid-range driving, the onboard engine acts strictly as a generator, supplying electricity to charge the battery while the electric motor continues to turn the wheels.
  • HEV ‘Parallel’ Mode: Under heavy acceleration or high-speed cruising, the petrol engine mechanically couples to the drivetrain, providing direct propulsion to the wheels alongside the electric motor.

The DM-i platform pairs advanced electric motor hardware with a highly specialised internal combustion engine optimised for thermal cycling:

  • Xiaoyun 1.5L Engine: The platform utilises a dedicated 1.5-litre naturally aspirated petrol engine that achieves an industry-leading thermal efficiency of 43.04 percent.
  • Super Hybrid Blade Battery: Power is stored in a specialised iteration of BYD's proprietary Lithium Iron Phosphate (LFP) Blade Battery, engineered for structural safety, puncture resistance and high thermal stability.
  • Fuel Economy: Under standard test conditions, the powertrain achieves a low consumption rate of 4.8-litre per 100 km (approximately 20.8 kmpl).
  • Acceleration: The Electric Hybrid System (EHS) delivers seamless, single-speed acceleration, enabling a zero to 100 kmph sprint time of under 5.5 seconds in its high-performance configurations.

Initially entering India in 2007 to build electric buses and commercial chassis, BYD India has scaled its passenger vehicle presence with models including the e6, Atto 3, Seal, eMax 7 and Sealion 7. The company supports its local assembly operations through two manufacturing facilities spanning over 140,000 square meters, representing an investment of more than USD 200 million.

Rajeev Chauhan, Head of the Electric Passenger Vehicles Business, BYD India, said, "The introduction of DM-i technology marks a pivotal step in our commitment to making sustainable mobility more versatile and accessible for Indian consumers. By enabling electric-first driving for daily use while seamlessly supporting long-distance travel, DM-i addresses some of the most pressing barriers to the adoption of sustainable motoring in India. With this innovation, we are bringing a new technology to Indian consumers, and also shaping a smarter, more flexible pathway towards sustainable transportation."

Sun Mobility Unveils Battery Swapping Solution For Buses At Prawaas 5.0

Sun Mobility - Tata Starbus 12m EV

Sun Mobility has introduced a modular multi-battery swappable solution for heavy electric vehicles, showcased on the Tata Starbus 12m EV platform at the Prawaas 5.0 exhibition in Gandhinagar.

The system aims to address barriers to fleet electrification, such as charging downtime and upfront vehicle costs. It enables the simultaneous swapping of two batteries in under five minutes. The architecture supports 50 kWh and 100 kWh configurations and is compatible with vehicles ranging from 3T to 55T gross vehicle weight. Through a Battery-as-a-Service (BaaS) model, operators pay for energy consumption rather than purchasing the battery pack.

Chetan Maini, Co-Founder and Chairman, Sun Mobility, said, "When we founded Sun Mobility, our vision was to make electric mobility as convenient, scalable, and economically viable as conventional transport by reimagining energy infrastructure. The unveiling of the world's first Modular Multi-Battery Swappable Solution demonstrated with Tata Starbus EV at Prawaas 5.0 marks a defining milestone in that journey. We believe the modular multi-battery swapping solution has the potential to unlock large-scale electrification across the commercial vehicle ecosystem by delivering a cost-effective and operationally efficient energy solution for diverse applications. As India accelerates its transition to clean mobility, technologies designed and built here can not only transform commercial transportation at home but also position India as a global leader in next-generation electric mobility solutions."

Ashok Agarwal, CEO, Sun Mobility HEV, added, “The next phase of electrification will not be defined solely by vehicles, but by the energy ecosystems that power them. Our showcase of World’s first Modular Multi-Battery Swappable Solution on the Tata Starbus EV platform demonstrates how one battery swapping platform can serve staff, city transit, and intercity fleets alike, without compromising on affordability or operational reliability. We see this as a real step towards mass adoption of EVs in commercial transportation.”

The system operates on an intelligent network that tracks battery health, location and energy usage. It also utilises a digital twin platform to support predictive maintenance and fault diagnosis. The technology is developed in-house and is intended to be OEM-agnostic, supporting bus and truck segments from 7 to 13.5 metres and 3T to 55T gross vehicle weight.
